An engagement ring is more than a jewel — it is a promise, a legacy, and a reflection of personal style. Among the many decisions you will make when choosing the perfect ring, few are as meaningful as selecting the shape of the diamond. While most jewellers only highlight the popularity of the round brilliant cut, at Prins & Prins, we believe every shape has a story, and every client deserves to explore the full range.
From the timeless sparkle of the round to the elegance of the oval and the bold geometry of the princess cut, each diamond shape carries its own beauty, symbolism, and character. Understanding these differences is the first step in finding a ring that genuinely resonates with you.
At our showroom in Cape Town’s historic Huguenot House, clients can view and compare expertly cut, independently certified natural diamonds in every shape imaginable. This guide explains the most popular diamond cuts and how to choose the one best suited to your engagement ring design.
The Round Brilliant Cut: Timeless Perfection
The round brilliant cut is the world’s most iconic diamond shape and remains the most popular choice for engagement rings. With 57 or 58 facets angled to precise proportions, it maximises brilliance, fire, and scintillation. Round Brilliant Cut is the shape that delivers the sparkle many clients imagine when they think of diamonds.
Its versatility makes it ideal for everything from a classic solitaire to more intricate halo or three-stone designs. A round brilliant diamond complements all hand shapes and settings, which is why it continues to be the preferred choice for generations.

Oval-Cut Diamonds: Modern Elegance
For those who love the brilliance of a round but want something less traditional, the oval-cut diamond offers the perfect alternative. Its elongated silhouette creates the illusion of greater size, and it flatters the hand by making fingers appear longer and more slender.
Oval-cut diamonds balance modern style with classic elegance. They shine in solitaire settings and adapt seamlessly to vintage-inspired designs. Style-conscious brides in Cape Town increasingly choose this shape for its sophistication and grace.

Cushion-Cut Diamonds: Romantic Glow
The cushion-cut diamond combines a square or rectangular shape with rounded corners, resembling a pillow — hence its name. Known for its romantic and vintage appeal, the cushion cut has been admired for centuries and remains a favourite for those seeking timeless charm.
Unlike the precise brilliance of the round, cushion-cut diamonds offer a soft, romantic glow. Their larger facets enhance colour and depth, making them an ideal choice for those who appreciate warmth and personality in their diamond.
The cushion cut suits antique-inspired settings and pairs beautifully with coloured gemstones, making it a versatile option for bespoke designs.
Princess Cut: Bold and Contemporary
The princess cut is defined by its clean, square shape and sharp angles, delivering both brilliance and a modern, architectural feel. Second only to the round brilliant in popularity, it is the perfect choice for those who prefer sleek, contemporary jewellery.
Princess-cut diamonds are particularly efficient when it comes to yield from the rough crystal, which often makes them more affordable per carat than round diamonds. They sparkle brightly and stand out in solitaire settings, though they are equally striking when paired with side stones.
This shape is ideal for clients who want a modern engagement ring that balances brilliance with bold design.

Emerald Cut: Refined Sophistication
The emerald cut is one of the most sophisticated of all diamond shapes. Its rectangular step-cut facets and open table showcase the diamond’s clarity and structure rather than fiery brilliance. Instead of dazzling sparkle, it offers a serene “hall of mirrors” effect, exuding understated elegance.
Emerald-cut diamonds have long been associated with refined taste, often chosen by those who value subtlety over extravagance. Because of its transparency, clarity becomes especially important in this shape.
This cut suits Art Deco-inspired rings and sleek solitaires, making it a preferred choice for clients with a love for minimalism and heritage design.

Other Distinctive Shapes: Pear, Marquise, Radiant, and Heart
While round, oval, cushion, princess, and emerald cuts are the most requested, several other shapes allow you to express individuality.
- Pear-shaped diamonds combine the round and marquise for a teardrop effect, symbolising romance and uniqueness.
- Marquise diamonds are elongated with pointed ends, creating a dramatic presence and the illusion of a larger size.
- Radiant cuts combine the outline of an emerald with the brilliance of a round, offering the best of both worlds.
- Heart-shaped diamonds are the ultimate symbol of love, perfect for those seeking something truly distinctive.
Each of these shapes has its own charm and can be customised into bespoke engagement rings that reflect personal style and sentiment.
